Printed circuit board with embedded lateral connector

ABSTRACT

Printed circuit boards (PCBs) may include embedded lateral connectors. The embedded lateral connectors may be configured to enable components to quickly couple to or plug into a PCB, thus saving time to form connections. The embedded lateral connectors may also reduce weight and/or size by avoiding need for bulky tradition collections with conventional components (e.g., solders, external pin connectors, etc.). The connectors may include male connectors, female connectors, and/or mounting connectors. The connectors may be configured to connect multiple PCBs together, such as using a stacked configuration, which may enable reducing a volume of space needed in a housing for the PCBs.

BACKGROUND

Printed circuit boards (PCBs) are formed during a manufacturing process, and then often later modified to add components, such as surface-mounted processors and other components. Some components are added to PCBs by adding solder to create electrical connections. Other components may be added by bolting through apertures formed through a thin side of a PCB, which is typically less than a few millimeters thick. Both of these processes add weight to the overall system and add bulk by increasing an overall volume of the PCB, and in particular, a thickness of the finished PCB.

DETAILED DESCRIPTION

This disclosure is directed to printed circuit boards (PCBs) that include one or more embedded lateral connectors, which may be used to couple components to the PCB. The connectors (also referred to as an “interface” or a “coupler”) may be formed as apertures configured to receive a plug or other corresponding solid connector (i.e., female connectors), as plugs configured to engage connector receptacles (i.e., male connectors), or a combination of both. Unlike conventional connectors that engage a PCB through a top or bottom surface, the connectors described herein are positioned in the lateral sides of the PCB and thus can project into the PCB on the order of millimeters or centimeters since PCBs have larger width and length than a thickness. Typically, a thickness of a PCB is just a few millimeters in most situations. The connector(s) may be used for data transfer, for supply of power, and/or for other electronic functions

In accordance with one or more embodiments, layers used to form a PCB may be formed with one or more apertures or cutouts on some layers to accommodate placement of the embedded lateral connector(s) between at least some of the layers. The apertures may be formed by die cuts or removing material in other ways (e.g., milling, etc.), formed by printing each layer to exclude material in locations to form the aperture(s), or by other known techniques to form a layer with at least one aperture. A PCB may be formed using the layers. For example, an inner layer may be formed that includes a first planar side and a second planar side opposite the first planar side. A connector may be coupled to the inner layer such that an aperture with a longitudinal axis is oriented parallel with the first planar surface. An opening of the connector may be aligned with a side of the inner layer. The connector may create an electrical connection between the inner layer and contacts included in the connector that are configured to engage a plug. In other embodiments, the connector may be a plug, but may be formed in a similar manner. Next, a set of layers may be coupled to the first planar side of the inner layer and another set of layers may be coupled to the second planar side of the inner layer. The layers may then be adhered (e.g., glued, laminated, cured, etc.) to form a PCB having the connector embedded laterally in the PCB.

The apparatuses and techniques described herein may be implemented in a number of ways. Example implementations are provided below with reference to the following figures.

FIGS. 1A and 1B show a pictorial flow diagram describing an illustrative process to create an electronic device with a printed circuit board (PCB) that includes an embedded lateral connector. The process is illustrated as a collection of blocks in a logical flow graph, which represent a sequence of operations The order in which the operations are described is not intended to be construed as a limitation, and any number of the described blocks can be combined in any order and/or in parallel to implement the process.

FIG. 1A shows an illustrative process 100. At 102, an inner layer 104 may be formed. The inner layer 104 may include a planar layer 106 having a top planar side and a bottom planar side. The layer may include etched or otherwise formed metallic connections on the top planar side, the bottom planar side, or both. The layers, including the planar layer 104, may be formed of insulator material, such as fiberglass (reinforces epoxy resin), plastic, or other material commonly used to form PCBs, and may include conductive materials, such as copper foil or other metallic foil or material. The planar layer 106 may include an aperture or special feature that accommodates coupling of a connector 108 to the planar layer 106 such that at least part of the connector occupies space within the plane of the planar layer 106, which is referred to herein as an aperture or special feature. In some embodiments, the layers may be formed by an additive manufacturing process that utilizes three-dimensional (3D) printing. The additive manufacturing process may omit or refrain from adding material in certain areas to form apertures or special features. In some embodiments, the layers may be machined, die cut, or otherwise processed to remove material to form the apertures or special features. The connector may be coupled to the inner layer such that a longitudinal axis of the connector is oriented parallel with the top planar surface. If the connector includes an aperture, an opening of the connector may be aligned with a side of the inner layer. The connector may create an electrical connection between the inner layer and contacts included in the connector that are configured to engage another connector, such as a plug or complementary recess (if the connector is a plug).

At 110, additional layers may be formed to create a PCB. Top layers 112 and bottom layers 114 may be created, such as using same or similar techniques used to form the planar layer 106 described above. The layers may include etched or otherwise formed metallic connections on a top side, a bottom side, or both of each layer. In some embodiments, the top layers 112 and bottom layers 114 may be mirrored versions of one another. At least some of the top layers 112 may include first apertures 116 while at least some of the bottom layers 114 may include second apertures 118, which may be a mirrored version of the first apertures 116. The first apertures 116 and the second apertures 118 may accommodate the volume of the connector, which may reside in a cavity formed by the apertures after assembly of the layers with the inner layer 104.

At 120, the top layers 112, the inner layer 104 and the bottom layers 114 may be assembled such as by stacking the layers on top of one another. When assembled the first apertures 116 and the second apertures 118 may be in alignment and may accommodate the connector 108, which may be situated between at least some of the layers and at least partly with the apertures.

At 122, the layers may be adhered (e.g., glued, laminated, cured, etc.) together to form a PCB 124 that includes an embedded lateral connector 126.

FIG. 1B shows additional processes 128 that may be performed on the PCB 124 or with the PCB 124.

At 130, conventional components 132 may be coupled to a top surface of the PCB 124, a bottom surface of the PCB 124, or both. The conventional components 132 may be coupled by solder, by threaded connectors that extend through apertures that extend through all layers of the PCB 124 in the planar surface of the PCB 124, and/or by other convention techniques. The components may include capacitors, controllers, resistors, pin connectors, and/or other types of conventional components.

At 134, a component 136 may be coupled to the embedded lateral connector 126. The component 136 may include a complementary connector 138 that is complementary to the embedded lateral connector 126 that, when joined or coupled to the embedded lateral connector 126, creates an electrical connection between the PCB 124 and the component 136. The component 136 may be a power adapter, another PCB, a display, and/or any other type of electronic component that operates by electrical interaction with the PCB. In some embodiments, the embedded lateral connector 126 may include multiple contacts, such as rings or other types of contacts, which may be designated for electrical transmission of different signals. In various embodiments, multiple embedded lateral connectors may be used to couple to the component 136. The multiple embedded lateral connectors may be a same type or may be of different types, which may desirably limit coupling position/orientation with the component 136.

At 140, the PCB 124 may be coupled to a housing 142 of an electronic device 144. The housing 142 may secure the PCB 124, such as by couplers that engage embedded lateral mounting features in the PCB, which are discussed below.
